Autumn had different views on the Mortals than the other gods. Instead of wanting to cherish them and protect them, he did not care what happened to them. To his surprise, The seemingly "Do good everybody loves me" Universae shared this view with him, but, Universae's Ideals were more.. Destructive. Universae, The Head god of the Council, Secretly despised all of the mortals, and the gods, after his mate, Innis, the Goddess of the Void, Sacrificed herself to save the mortals by wrapping herself around a dying star, shattering her soul. But Autumn was different to him, he saw himself in Autumn, and decided to let him in on his plan to rid the world of the mortal dragons. He gave Autumn a piece of his soul, so they could communicate, and for when the time comes to attack. This shard of Universae's soul would make Autumn's corrupt form much more powerful.
